I am trying to figure out my VP-X Pro wiring to get as many things as possible their own circuits. I have it nearly figured out but I am left with the power plug being on a 5A circuit or running it separately from the VP-X. I like the idea of having it on the VP-X system for two reasons (uniformity of everything and at-a-glance current going through it). Is 5A enough? I am sure I could find some 12V device that draws 6A or even 20A if I try hard enough, but what's the chance I will bring a microwave with me? Has anyone been through this agony and made a decision that you're either happy or unhappy with?
